Background: The esebssiwaagoTQ method is applicable for the of study cell gene recombination events as the esebssiwaagoTQ is a measure of the intracellular pressure required to establish a horizontal reading frame for alignment of a gene and its intergene bases for maximal transcription and recombination enzyme activity. B-cell differentiation stages have recently been studied by gene esebssiwa...

a proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. this paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. for this aim, dst and pvt data of exploration and production wells of a supergiant offshore gas condensate reserv...

During meiosis, homologous chromosomes are brought together to be recombined and segregated into separate haploid gametes. This requires two cell divisions, an elaborate prophase with five substages, and specialized mechanisms that regulate the association of sister chromatids. This review focuses on plant chromosomes and chromosome-associated structures, such as recombination nodules and kinet...

In four distinct alstroemeria-infecting cucumber mosaic virus (CMV) isolates, additional sequences of various lengths were present in the 3' nontranslated regions of their RNAs 2 and 3, apparently the result of intra- and intermolecular recombination events. Competition experiments revealed that these recombined RNA 2 and 3 segments increased the biological fitness of CMV in alstroemeria.

Mice with transgenes containing an antibody H chain V region (VHDJH) gene were used in an analysis of the cis-acting elements required for hypermutation of immunoglobulin (Ig) V genes. These transgenes can somatically recombine with endogenous IgH DNA, leading to the formation of functional heavy (H) chains partially encoded by the transgenic VHDJH. The transgenomes in the five different lines ...

Maximum tiller number and productive tiller number are important traits for wheat grain yield, but research involving the temporal expression of tiller number at different quantitative trait loci (QTL) levels is limited. In the present study, a population set of 371 recombined inbred lines derived from a cross between Chuan-Nong18 and T1208 was used to construct a high-density genetic map using...

We present a new technique, which we call ‘texture unmapping’, and its application to image reconstruction. A parametric model of an image is made, and then subtracted from the image to leave a non-parametric component. The two components may then be reconstructed independently and then recombined to give a final reconstruction. Results of the new technique are given on a range of images.
